SONL housings have a deep reservoir that holds a large volume of oil, which means cooler oil and lower bearing operating temperatures. SONL housings also feature a robust, specially designed oil seal to prevent leaks.

Even cooler with SKF oil cooling cartridges

Bearings in fans situated in high-temperature environments often operate at their temperature limits. In such cases, a highly effective SKF oil cooling cartridge can be combined with an SONL housing to control operating temperatures. The SKF oil cooler is a closed loop system that can be connected to any water supply.
